7 Claims.

This invention relates to sash control and weather strips, more particularly to metallic weather strips.

The object of this invention is to provide a weather strip which not only forms a tight joint, and thus excludes the elements such as wind, rain, snow and air, but at the same time eliminates the use of the weights and cords so commonly found in window frames. The present invention may, however, be used with a window frame which is provided with weights and cords.

Another object of this invention is to have the weather strip extend from top to bottomof the frame so as to make a continuous, air-tight joint from top to bottom of the frame and at the same time eliminate any rattling.

Another object isto provide a weather strip which may be used with any type of sliding window and on any width jamb without making it necessary to cut the jamb or sash in order to install the weather strip.

A further object is to provide a weather strip of L-shape which is not fastened to either the jamb or the sash, but is frictionally held against the sash and the jamb by means of springs. Thus it will be seen that the weather strip forms a tight joint regardless of the position of the sashes;-

A full and complete understanding of the invention may be attained from a consideration of the following detailed description taken in connection with the accompanying drawings. It will be understood that while the drawings show a practical form of the invention I do not limit myself to such form because the said invention may be embodied in other forms.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters designate like or corresponding parts throughout the several figures.

Fig. 1 is a fragmentary View of a front elevation of a window. 7

Fig. 2 is a perspective view of the weather strip. 7 r

Fig. 3 is .a horizontal section taken substantially on the line 3-3 of Fig. 4.

Fig. 4 is a perspective view of a modified form of weather strip.

Fig. 5 is a modification showing a horizontal section similar to that shown in Fig. 3.

Fig. 6 is another modification in horizontal section showing the parting strips hollow and with raised ends, which are Referring to the drawings in detail, a conventional window is shown consisting of the inner trim I and the outer trim 2 between which is the jamb 3 having a recess which is adapted to hold the parting strip 4, which acts as a guide for the lower sash 5 and the upper sash 6, both of the sashes holding window panes'l.

The weather strip as shown in Figure 2 comprises an angularly formed strip of metal, the

slightly exaggerated.

angle thereof extending longitudinally throughout its length. The weather strip may be made of any type of metal, however, it is preferred to make the strip out of some non-corrodible metal, such as brass or aluminum. These metals besides being non-corrodible are more or less resilient.

The weather strip when in position extends from top to bottom of the frame and has a certain amount of freedom as it is not attached in anyway to the frame. 7

The angularly formed strip has two faces, the wider face -9 being inserted between the jamb 3 and the sashes 5 and 6, while the narrower face 8 is held between the inner side of the lower sash and the inner stop It. In connection with'the upper sash the narrow face 8 is held between the outer side of the upper sash and the inner side of the outer stop ll. As shown in Figures 1 and 3, the stop members id and H extend the whole length of the frame and are provided with two or more recesses l2 in which are held coiled springs l3, which are adapted to bear against the narrow face 3 of the L-shaped member and thus hold the weather .strip by means of friction tightly against the sash and jamb.

It will be observed that the face 9 of the L-shaped member does not engage the parting strip 4, thus allowing for any expanding or contracting of the sashes.

By the present invention it is possible to eliminate entirely the use of weights and cords as the weather strip holds the sashes in any'position in which they may be put. I have also pro-.- vided a cam-shaped locking device it by which it is possible to lock the sash from the inside in any position, so that it cannot be raised or, lowered from the outside. This locking device will also help to make a tight joint as well as provide the window with a double look when it is in its closed position.

Figure i shows a modified form of weather strip in which the face g is provided with extensions l5, which may be either welded, riveted, or screwed on to the face, or if desired these extensions maybe made as an integral part of the weather strip.

In the modified assembly shown in Figure 5, and in which the weather strip shown in Figure 4 is adapted to be used, it will be observed that the jamb' 3 is provided with two or more holes it, which are more or less tapered, extending inwardly a substantial distance from the side of the jamb and terminating in a slot ll, which extends at right angles to said hole. The slot I1 is bored inwardly from the inner face of the jamb and is adapted to receive the extensions l5 of the weather strip. Although the slot I! in the present form is shown terminating where it meets the hole 5, it may extend beyond the end of the hole 16 or all the way through the jamb if conditions require it. A coiled spring 18 is inserted in the hole It through the open end of the hole and is held inadjusted position by means of a set screw or adjustable plug l9. It will thus be apparent that by adjusting the plug or screw I9, which may be adapted to be held in a sleeve 20, the spring will engage the extension 15, which will frictionally hold the weather strip against the sash and thus form a tight joint.

In the modified form of this invention it is necessary that the spring assembly be installed while the trim is not in place. In the form disclosed in Figures 1 and 3 it is only necessary to remove the stop in order to install the weather strip.

In the form shown in Figure 6 a hollow parting strip may be used, which is made preferably of metal or some similar material. This parting strip has base flanges 30 with their longitudinal edges slightly raised above the plane of the body of the flange. The flanges, and thereby the parting strips, are secured to the jamb by suitable fasteners 32. In this construction the inner ends of the weather strip 9 fit under the raised ends 35 of the flanges, thus insuring a weather tight and wind proof joint.

Having thus described this invention, what I claim and desire to secure by Letters Patent is:

1. In a window frame including a jamb, inner and outer stops, a parting strip, upper and lower sashes guided by said parting strip, and adapted to slide in said frame, a weather strip of angular shape extending from top to bottom of said frame and loosely and freely mounted therein, one face of said weather strip being frictionally held between the jamb and the sash, while the other face of said weather strip is frictionally held between the stop and a sash, coiled springs engaging said weather strip, and projecting the same inwardly and thereby forming a tight joint between the weather strip and the cash and the stop and the sash, from top to bottom of said frame.

2. In a window frame including a jamb, inner and outer stops, a parting strip, upper and lower sashes guided by said parting strip, and adapted to slide in said frame, a weather strip of angular shape, having an angle extending longitudinally throughout its length, and having two smooth faces extending at right angles to one another, said weather strip extending from top to bottom of said frame, and loosely and freely mounted therein, one face of said weather strip being frictionally held between the jamb and the sash by, means of coiled springs, but out of engagement with the parting strip, while the other face of said weather strip is frictionally held between the stop and the sash, thereby forming a tight joint between the Weather strip and the sash, and the stop and the sash, from top to bottom of said frame.

3. In a window frame including a jamb, inner and outer stops, a partin strip, upper and lower sashes guided by said parting strip, and adapted to slide in said frame, a weather strip of angular shape having an angle extending longitudinally throughout its length, thus forming an L- shape, said L-shape member having two smooth faces extending at right angles to one another, one of said faces being wider than the other, said wider facebeing frictionally held between the jarnb and the sash by means of coiled springs, but out of engagement with said parting strip, while the narrower of said faces is frictionally shape having an angle extending longitudinally throughout its length. said weather strip extending from top to bottom of said frame, one

face of said weather strip being frictionall held between the jamb and the sash, while the other face of said weather strip is frictionally held between the stop and the sash, by means of coiled springs held by said stop, thereby forming a tight joint from top to bottom of said frame between the stop and the sash, and the weather strip and the sash.

5. In a window frame including a jamb, inner and outer stops, a parting strip, upper and lower sashes guided by said parting strip, and adapted to slide in said frame, a weather strip of angular shape, one face of said weather strip being provided with an extension, entering a recess in said jamb, and engaging a spring in said recess, thereby forming a tight joint between said weather strip and said sash.

6. In combination a window frame comprising a jamb, inner and outer stops, upper and lower sashes, a parting strip guiding the sashes and separating them from each other, said parting strip having base flanges with their end edges out of the plane of the body of the flanges and spaced from the jamb to form longitudinal recesses, a weather strip of angular shape mounted between on of the stops and the sash, with its inner end engaging beneath the one end edge of the base flanges of the parting strip and entering the longitudinal recess and spring means for urging the weather strip into operative position.

7. In combination a window frame comprising a jamb, inner and outer stops, upper and lower sashes, a parting strip directing the sashes and separating them from each other, longitudinal flanges adjacent the base of the parting strip with their end edges out of the plane of the body of the flanges and spaced from the jamb to form a longitudinal recess with the jamb, a weather strip of angular shape mounted loosely and freely between one of the stops and the sash, with its inner end engaging beneath one end edge of the base flanges of the parting strip and projecting into the longitudinal recess, and spring means for urging the loosely mounted weather strip into engagement with the sash and projectin -its inher end beneath the longitudinal flange of the base and into the longitudinal recess to provide a weather tight joint.
